Faglige interesser

Naturen er kilde til mange av de legemidlene vi bruker i dag, både i form av isolerte naturstoffer, derivatiserte naturstoffer eller er inspirasjonskilde for syntetiske legemidler. I tillegg brukes ekstrakter og uttrekk fra planter som medisin, både i tradisjonell plantemedisin og i moderne bruk av plantebaserte legemidler.

Min forskningsinteresse dreier seg om isolering og identifikasjon av naturstoffer fra medisinplanter eller næringsmidler. Antioksidant og anti-inflammatoriske effekter av de isolerte naturstoffene studeres også, andre effekter studeres i samarbeid med andre forskere. Hensikten med dette arbeidet er å kunne identifisere innholdsstoffer med biologiske effekter som kan bidra til å forklare den folkemedisinske bruken, samt at det vil gi kunnskap om de mekanismene som kan være involvert i effekt.

Pågående forskningsprosjekter:

  • Antioksidant og antidiabeteseffekter av ekstrakter og fenoliske forbindelser fra norske bær
  • Isolering av karakterisering av innholdsstoffer fra medisinplanter brukt mot kognitive lidelser
  • Metabolomikk og DNA barcoding av indiske medisinplanter
  • Antimalaria effekter av afrikanske medisinplanter
